A more thorough explanation:

Definition: To delay or put off to a later time. It can also mean to give less importance to something or to temporarily or permanently stop the consideration of a main motion in parliamentary law.

Examples:

• We had to postpone the meeting until next week because the boss was sick.
• The construction of the new building was postponed due to budget constraints.
• The company decided to postpone the launch of their new product until the market conditions improved.

The examples illustrate how postponing something means delaying it to a later time.
